Stacked grid solar cell sheet, solar cell, and photovoltaic module

Abstract

Provided are a stacked grid solar cell sheet, a solar cell, and a photovoltaic module. The stacked grid solar cell sheet includes a cell sheet substrate. A stacked grid structure is provided on a first surface of the cell sheet substrate. The stacked grid structure includes grid lines and metal wires, where the grid lines are provided on the cell sheet substrate and distributed parallel to each other at equal intervals, and the metal wires respectively cover the grid lines. A second stacked grid structure, a conventional electrode structure, or a back electrode is provided on a second surface of the cell sheet substrate. At least one current collection structure is provided on the cell sheet substrate. A current collection structure of the at least one current collection structure is perpendicularly connected to the metal wires.
